The student has included five supporting documents, clearly labeled and marked in the "Works Cited" section. These documents are relevant and sufficiently in-depth, providing a range of ideas and views regarding the topic. Additionally, the student has assessed the validity and reliability of the supporting documents in the methodology, addressing potential bias and ensuring a comprehensive exploration. However, one of the supporting documents was published more than three years prior to the submission of the IA, and the student did not highlight the parts of each supporting document that relate directly to their IA, as well as not including any attachments of the supporting documents at the end of the work.
